#coupling: if you change the size of the image, you need
# to adjust kernel/init/user/boot/xxx/boot.rc line about
# 'part dos 1 204801' where the last number must match the
# number of sectors in dosdisk.img (see the output of 
# 'dd if=dosdisk.img of=/tmp/xxx' to see the number of sectors)
# and remake the kernel file (because boot.rc changed)
# In theory you should also update MISC/pc/bootsector but this may
# not be necessary in practice.

#pad: I need the quote arount the 'xx=yy' below because of rc
